DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] Reference will now be made in detail to the embodiments of
the present disclosure. Referring to FIGS. 1-8, an electrical
connector assembly 1000 is essentially a board-to-board connector
set including a receptacle connector 100 mounted upon one printed
circuit board (not shown), and a plug connector 200 mounted upon
another printed circuit board (not shown). The receptacle connector
100 includes an insulative housing 1, a plurality of contacts 2
retained to the housing 1, and a metallic shield 3 covering the
housing 1. The plug connector 200 includes an insulative casing 4,
a plurality of terminals 5 retained to the casing, and a metallic
shell 6 enclosing the casing 4.
[0014] In the receptacle connector 100, the housing 1 includes a
base 11 and an island 12 extending from the base 11, and a
peripheral wall 14 surrounding the island 12 to form a tubular
receiving cavity 13 therebetween. The contacts 2 are arrange with
two rows. The peripheral wall 14 includes a pair of long side walls
141 and a pair of short side walls 142. The shield 3 covers both
the side walls 141 and the side walls 14 continuously. The shield 3
further includes the inner part 32 extending from the outer part 31
and covering the interior face 1411 of the first side wall 141 with
a plurality of spring tangs 321 extending into the tubular
receiving cavity 13. The two rows of contacts 2 are respectively
disposed upon two opposite sides of the island 12 directing to the
corresponding long side walls 141. Each contact 2 includes a
retaining section 21, a soldering section 23 extending from the
retaining section 21 an exposed outside of the long side wall 141,
and a resilient contacting section 23 extending from the retaining
section 21 and exposed upon the island 12 and extending into the
tubular receiving cavity 13. The shield 3 further includes a pair
of soldering legs 33 by two short side walls 142. The long side
wall 141 forms blocks 1411 engaged within the holes 311 of the
shield 3.
[0015] In the plug connector 200, the insulative casing 4 includes
a base 41 and a circumferential wall 43 extending upwardly from the
base 41 to form a mating cavity 42. The terminals 5 are arranged
with two rows. The casing includes a pair of large walls 431 and a
pair of small walls 432. The shell 6 forms holes 61 to receive the
corresponding blocks 4311 formed on the large side wall 431 for
securing the shell 6 to the casing 4. The terminals 5 includes a
retaining portion 51 retained to the casing 4, a soldering portion
52 extending from the retaining portion 51 and outside of the large
side wall 431, and a planar contacting portion 53 extending from
the retaining portion 51 and exposed upon the an interior surface
of the large side wall 431. The shell 6 further includes a pair of
soldering pads 62 by two sides of the small side walls 421.
[0016] Notably, during mating the island 12 is inserted into the
mating cavity 42 and the circumferential wall 43 is received within
the tubular receiving cavity 13. The contacting sections 23 connect
to the corresponding contacting portions 53. The spring tangs 321
abut against the shell 6. The shielding effect is perfected due to
the continuous surrounding/shielding structure on each
connector.
[0017] The feature of the invention is to provide the anti-EMI
structures between the receptacle connector 100 and the plug
connector 200. The receptacle connector 100 further includes a pair
of shielding plates 7 assemble within the island 12 to separate the
two rows of contacts 2 in the transverse direction. In another
embodiment, the pair of shielding plates 7 may be unitarily formed
as one piece. The plug connector 200 further includes a shielding
blade 8 assembled to the base 41 and extending into the mating
cavity 42 to separate the two rows of terminals 5. During mating,
the shielding blade 8 is sandwiched between the pair of shielding
plates 7 so as to efficiently isolate the mated contacts 2 and
terminals 5 on one side of the island 12 from those on the other
side. In this embodiment, the island 12 includes a pair of
retention slots 121, i.e., the first retention slot 1211 and the
second retention slot 1212, and an insertion slot 122
communicatively between the pair of retention slots 121. The island
12 housing 1 further includes a top face 15 and a bottom face 16.
The retention slots 121 extend from the bottom face 16 and
terminates before reaching the top face 15 while the insertion slot
122 extends through both the top face 15 and the bottom face 16.
The shielding plate 7 includes a retention section 71 retained in
the retention slot 121 and a spring finger 72 extending into the
insertion slot 122. The retention section 71 includes interference
sides 710 engaged within the retention slot 121. The shielding
plate 7 forms a mounting side and an insertion side opposite to
each other, and includes the soldering legs 73 on the mounting
side. The shielding plate 7 further includes an arc section 74 at
the top opposite to the mounting side in the vertical direction and
opposite to the spring fingers 72 in the transverse direction, One
shielding plate 7 includes the first shielding part 711 includes a
planar first retention section 7111 retained in the first retention
slot 1211, and a first abutment section 7112 extending from the
first retention section 7111 into the insertion slot 122.
Similarly, the other shielding plate 7 includes a second shielding
part 712 includes a planar second retention section 7121 retained
in the second retention slot 1212, and a second abutment section
7122 extending from the second retention section 7121 into the
insertion slot 122.
[0018] During mating, the shielding blade 8 is inserted into the
insertion slot 122 and sandwiched by the first abutment section
7112 of the first shielding part 711 and the second abutment
section 7122 of the second shielding part 712 in the transverse
direction. In this embodiment, the lengthwise dimension of the
shielding plate 7 and the shielding blade 8 are similar to the
dimension of the housing 1 and the casing 4, and during mating, the
height of the connected shielding plate 7 and shielding blade 8 is
similar to the assembled housing 1 and casing 4, thus assuring
reliable shielding effect thereabouts.
[0019] Another feature of the invention is regarding the shield 3
having top frame structure to cover the top face of the housing 1,
and the outer part 4 extends downwardly from four edges of the
frame structure. The shell 6 is also configured as well.
[0020] While a preferred embodiment according to the present
disclosure has been shown and described, equivalent modifications
and changes known to persons skilled in the art according to the
spirit of the present disclosure are considered within the scope of
the present disclosure as described in the appended claims.
